The leader of Hezbollah, Sayyed Hassan Nasrallah, said on Tuesday his Lebanese Shia Muslim group opposed U.S-led air strikes on Syria.

"We are against American military intervention and an international coalition in Syria, whether that (action) is against the regime or IS," Nasrallah said in a speech aired on Hezbollah-run al-Manar television.

Al-Qaeda's Syria franchise on Friday released a video showing nine Lebanese army and police hostages it said could pay the price for the Shia group Hezbollah's military intervention in the Syrian conflict.

The al-Nusra Front video, entitled "Who Will Pay the Price?", shows the abducted members of Lebanon's security forces condemning Hezbollah, which has fought alongside President Bashar al-Assad's regime against rebels.

Prime Minister Benjamin Netanyahu said Israel agreed to a permanent truce in its 50-day Gaza war with Hamas in order to keep focused on the threat from regional militants.

"We fought for 50 days and we could have fought for 500 days, but we are in a situation where the Islamic State is at the gates of Jordan, Al-Qaeda is in the Golan and Hezbollah is at the border with Lebanon," Netanyahu said in an address on public television.

His remarks come as the United States, Israel's chief ally, is calling for a global coalition to fight the jihadists who have set up an Islamic "caliphate" in areas they have overrun in Syria and Iraq.

Quotes from the speech Hassan Nasrallah, the secretary-general of the Lebanese group Hezbollah, made on Friday:

"At the end of the day, three factors will decide the winner of the battle [between Palestinian factions and Israel]: the field, people’s steadfastness and the political prudence. What is targeted in Gaza is resistance, its arms, its steadfastness and the hope it gives to people. As Gaza has won victory; as we are on day 18 and the Zionists, backed by the whole world, are not able to achieve their goals from the war, it is a living proof that the resistance has triumphed."

"Israeli failure is clear; achievements by the resistance are evident. Israelis' fear of failure caused them to lower the ceiling of their demands as they learned the lessons from 2006 war on Lebanon. It is also a proof of the failure of their intelligence on the capabilities of the resistance."

Hezbollah and the Lebanese resistance stand firmly on the side of the Intifada and the Palestinian people's resistance, and support Hamas' strategy and the just conditions it has set to end the conflict.

President Assad's landslide election victory means that his civil war foes can no longer call for his departure as a precondition for peace, Hezbollah leader Hassan Nasrallah said on Friday.

The leader of the Lebanese group that has sent fighters to back the president, described the vote as a victory for Syria.

"This election tells the opposition and all regional countries and the world that any political solution in Syria begins and ends with President Bashar al-Assad," Nasrallah told supporters via a video link.

"You can no longer put the resignation of the president as a pre-condition."
